RF capacitive device/Low price, economical and durable liquid level switch

working principle

CWASeries RFCapacitive object/The liquid level switch uses the capacitance formed between the sensing electrode and the grounding electrode, with the measured material as the medium. When the material covers the sensing electrode

When using electrodes, the measured capacitance value will increase and output a switch signal when it reaches the set value.
